DETAILED DESCRIPTION

Various embodiments are generally directed to techniques, systems, and processing flows to generate, transmit, scan, and or utilize an aggregated matrix code, e.g. such as an aggregated barcode. In various embodiments, the aggregated matrix code can have one or more swappable components, e.g. one matrix code corresponding to a group and one matrix code corresponding to an individual, e.g. a user-specific barcode that can be overlaid on a group or base barcode, where the user-specific matrix code, e.g. barcode, can grant access to one or more features of an application, network, and/or device and where the aggregated matrix code, e.g. barcode, can grant access to even more features of an application, network, and/or device. In various embodiments, either matrix code, e.g. barcode, is swappable, which means that, in addition to enhancing the security of accessing one or more features of a device or network, the versatility and flexibility of accessing applications is increased, as an individual may utilize his or her individual matrix code, e.g. barcode, with multiple group or base matrix codes, e.g. barcodes, and vice-versa, where the aggregated variations offer access to different features with respect to one or more applications, devices, and/or networks.

Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements. In the following description, for the purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form to facilitate a description thereof. The intention is to cover all modifications, equivalents, and alternatives within the scope of the claims.

FIG. 1 depicts a schematic of an exemplary system 100, consistent with disclosed embodiments. As shown, the system 100 includes one or more mobile devices 110 and/or 110′ that can interact with a user 102 a and/or user 102 b, respectively, and a server 120 via any suitable network 130 (e.g. internet, intranet, or any other suitable network). The mobile devices 110 are representative of any type of network-enabled computing devices, such as smartphones, tablet computers, wearable devices, laptops, portable gaming devices, and the like. The server 120 is representative of any type of computing device, such as a server, workstation, computer cluster, cloud computing platform, virtualized computing system, and the like. It is noted that the applications, components, and/or features of 110 and 110′, as shown and pursuant to various embodiments, can be substantially identical, and for convenience, the description of device 110 is applicable to 110′; however, it is noted that variations are possible according to other embodiments, etc.

As shown, a memory 111 of the mobile device 110 includes an instance of an operating system (OS) 112 and a processor 119 may execute one or more operations associated with the applications of the operating system (OS) 112 and/or perform any other suitable operation associated with processor activity, including comparison operations and executing instructions associated with memory 111. Example operating systems 112 include the Android® OS, iOS®, Linux®, and Windows® operating systems. As shown, the OS 112 includes one or more applications, including an authentication or verification application or service 114 (hereinafter referred to as “authentication application” for convenience), one or more other applications 115, one or more access applications 116, a barcode application 117, and a decryption mechanism 127.

The authentication application 114 is generally configured to perform one or more operations related to authenticating a user 102, including but not limited to determining when a user requires authentication for a transaction, service, or accessibility request, including the accessibility of information associated with credentials from one or more applications of and/or related to a host device, e.g. server 120 and related to authenticating a user 102 a and/or 102 b with respect to one or more applications hosted by the server and accessible by the users 102 a and/or 102 b, e.g. access application 116 and/or other applications 115. For example, the authentication application 114 may receive any suitable decryption mechanism 127 from a management application 123 of the server 120, where the decryption mechanism 127 can be related to an encryption mechanism 125 and can facilitate a decryption operation associated with the encryption operation of the encryption mechanism, e.g. such as a token for decrypting a barcode in association with a scan thereof and/or a key to decipher ciphered text.

In various embodiments, the encryption mechanism 125 can be embodied in the form of one or more matrix codes, e.g. barcodes 103 a, 103 b, 103 c, and/or 103 d, and the authentication application 114 can receive a single, multiple, or continuous stream of decryption mechanisms 127 from the server 120 in order to decrypt the encryption associated with the encryption mechanism, e.g. the authentication application 114 can utilize a decryption token in relation with a scan of one or more matrix codes, e.g. barcodes 103 a, 103 b, and/or 103 c associated with a scan (e.g. facilitated by a barcode application 117 instructing a scanner 118 to scan a suitable matrix code, e.g. barcode) of the same and/or a static or alternating cipher associated ciphered text. Once the authentication application 114 decrypts the encryption mechanism 125 (e.g. after scanning the one or more barcodes), then access to one or more features associated with access application 116 and/or other applications 115 can occur, e.g. in various embodiments, once decrypted, one or more features of any one of or more of access application 116 and/or other applications 115 can become available to the one or more users 102 a, 102 b.

In various embodiments, the management application 123 of the server can transmit an encryption scheme, e.g. the encryption mechanism 125 is configured and transmitted accordingly, where the matrix codes, e.g. barcodes, 103 a and 103 b are user-specific matrix codes, e.g. barcodes, to users 102 a and 102 b, respectively, and where the matrix code, e.g. barcode 103 c, is a base or group barcode 103 c that is common to both users 102 a and/or 102 b as a result of being part of the same group, which can be combined with the individual matrix codes, e.g. barcodes 103 a and/or 103 b, to form an aggregated matrix code, e.g. barcode 103 d for user 102 a and barcode 103 e for user 102 b. In various embodiments, as stated and implied above, the management application 123 can transmit the decryption mechanism 127 that, upon scanning the one or more codes 103 a, 103 b, 103 c, 103 d, and/or 103 e, one or more features of access application 116 and/or other applications 115 are accessed. In various embodiments, the authentication application 114 can access or utilize the transmitted encryption mechanism 125 to generate any one of the one more codes 103 a, 103 b, 103 c, 103 d, and/or 103 e, including forming an aggregated barcode 103 d and/or 103 e by instructing the barcode generator 117 to do the same. In various embodiments, the authentication application 114 can instruct the barcode generator 117 to utilize the transmitted encryption mechanism 125 to create a unique, individual barcode, for each user 102 a and/or 102 b, where the individual barcodes, e.g. 103 a and/or 103 b, are uniquely assignable and unique to the particular individual, e.g. 103 a for user 102 and 103 b for user 102 b. Thereafter, in various embodiments, (as discussed in greater detail below), one or more aggregated barcodes 103 d and/or 103 e can be created utilizing a common base or group code 103 c.

In various embodiments, the management application 123 can transmit the encryption mechanism 125 to one or more devices to generate the one or more barcodes 103 a, 103 b, 103 c, 103 d, and/or 103 e. In various embodiments, the authentication application 114 of the mobile device, and/or any other suitable application of another device that generates one or more barcodes that can be used in an aggregated scheme as outlined herein, utilizes the encryption mechanism 125 to instruct the barcode generator 117 to generate one or more barcodes and/or generated an aggregated scheme or barcode. In various embodiments, the generation of the aggregated barcode 103 d and/or 103 e can be at the bit-level, e.g. the encryption mechanism 125 of the server 120 is configured by the management application 123 to be able to generate a first set of encrypted bits for an individual matrix code, (and the authentication application 114 of the mobile device 110 utilizes the scheme to provide appropriate instructions to the barcode generation application 117), where the bits are specific to the user, e.g. barcode 103 a specific to user 102 a, and a second set of encrypted bits for the group code 103 c that are common for a group, e.g. user 102 a and user 102 b, and where the authentication application 114 can instruct the barcode application 117 to generate the user-specific barcode, e.g. 103 a and/or the group and/or base barcode 103 c by utilizing the first and/or second bits, as needed, and where an aggregated matrix code, e.g. barcode 103 d and/or 103 e, is required, combine the first and second bits to form the aggregated code or codes 103 d and/or 103 e.

In various embodiments, the aggregating of an individual matrix code and a base code to form an aggregated code can be done by actually overlaying generated barcodes on top of one another. In various embodiments, the management application 123 can configure one or more encryption mechanisms 125 to be transmitted such that a first matrix code, e.g. either an individual code, e.g. individual code 103 a and/or 103 b, and/or a base code 103 c is generated, e.g. by the authentication application 114 instructing the barcode application 117 to do so. The generated barcode can be displayed on the display 140, where authentication application 114 of the mobile device and/or the management application 123 of the server, as part of the barcode generation process with respect to the barcode application 117, configures or angles the displayed barcode so that a second barcode (or more) barcode, e.g. the one of the base or individual barcode not initially generated on the display, being overlay-able on the displayed barcode, thus forming an aggregated barcode.

For simplicity, the above discussion, assumes that the mobile device 110 generating the device will contain or be attached to or otherwise associated with the components for receiving the encryption associated with the matrix codes, e.g. barcodes, the components necessary to generate the barcodes, display the barcodes and scan the barcodes. However, in various embodiments, one or more components can be associated with another devices, including a device that independently scans the barcodes and/or independently generates one or more of the user-specific barcodes, the base or group barcodes, and/or the aggregated barcodes. In various embodiments, for example, the mobile device 110 can receive the encrypted mechanism for the individual barcode associated with a user, e.g. user 102 a, and generate and display the user specific barcode, e.g. 103 a, and another device (not shown) can generate and display the common or base barcode (e.g. by receiving the relevant encryption mechanism from the server 120, and the individual barcode from each user can be overlaid by projection or any other suitable technique, such that a scan of the aggregated barcode associated with the overlaying (by yet another distinct device, e.g. distinct scanner,) or by a component of either one of the mobile device and the device associated with the base or group code). In various embodiments, as stated and implied above, the overlaying of the barcodes, with or without requiring a subsequent scan, can grant access to one or more features associated with access application 116 and/or other applications 115. In various embodiments, the encryption mechanism, e.g. 125, can be automatically configured to result in decryption when two barcodes are overlaid over one another, e.g. a base code 103 c and an individual code 103 a, by defining the key of encryption as the orientation and/or angular relationship between the one or more codes, which in turn results in the access to one or more (e.g. a first and/or second and/or third, etc.) feature associated with access application 116 and/or other applications 115. In various embodiments, this can be advantageous in offering a setting where multiple users, e.g. a conference room, can enter and overlay their individual code on top of the base code to access individual specific information and information common to the group. It should be noted that although various embodiments as discussed herein refer to access application 116 and/or other applications 115, the access granted with respect to the decryption, e.g. scanning and/or overlaying, of barcodes as described herein can be configured to grant access to other applications, whether with respect to mobile device 110 and/or 110′ and/or whether hosted by server 120, devices, networks, and/or features as may be suitable.

In various embodiments, the user-specific matrix codes, e.g. barcodes 103 a and 103 b, can grant access (e.g. once scanned and decrypted) to a first feature or first set of distinct features with respect to access application 116 and/or other applications 115 for each user, e.g. account information that is unique to each user 102 a and/or 102 b in the account data 124. In various embodiments, the base or group matrix codes, e.g. barcodes 103 c, can also grant access to one or more features with respect to access application 116 and/or other applications 115, e.g. where those features are common and the same for a particular group, where the group can include user 102 a and/or user 102 b. In various embodiments, the combination of matrix codes, e.g. barcodes 103 a and 103 c to form barcode 103 d for user 102 a and barcode 103 b and 103 c to form barcode 103 e for user 102 b, e.g. aggregated barcode 103 d and aggregated barcode 103 e, respectively, grants each user additional features that can be unique to that individual with respect to access application 116 and/or other applications 115, e.g. based on the user's role in the group (e.g. manager, full-time employee, contractor, etc.). In various embodiments, the individual matrix code, e.g. barcode e.g. 103 a and/or 103 b, can grant access to various aspects of access application 116 and/or other applications 115, but the base code 103 c by itself cannot, where the individual matrix code, e.g. barcode 103 a and/or 103 b, provides access to information that is unique to the user for which the matrix code, e.g. barcode 103 a and/or 103 b, is assigned, e.g. account information that is user specific, and where the combination of the individual matrix codes, e.g. 103 a and/or 103 b, with the group or base matrix codes 103 c grants additional features with respect to the access application 116 and/or other applications 115.

In various embodiments, the individual matrix codes, e.g. 103 a and/or 103 b, cannot grant access to any features with respect to other applications 115 and/or access application, where the group or base code 103 c can grant access to the same features of the one more other applications 115 and/or access application 116, e.g. a set of group tasks that a set of employees, e.g. 102 a and/or 102 b, of an entity associated with server 120 part of the same team are to perform, and where aggregating the user specific codes 103 a and/or 103 b with 103 c to form aggregated codes 103 d and/or 103 e grants access to tasks that are specific to a particular employee part of the group, e.g. 102 a and/or 102 b. In various embodiments, only the aggregated matrix codes, e.g. barcodes 103 d and/or 103 e, can grant access to one or more features of other applications 115 and/or access application 116.

In various embodiments, where the encryption/decryption scheme is a barcode, the authentication application 114 can instruct the barcode application 117 to facilitate the scanner 118 for scanning the one or more barcodes 103 a, 103 b, 103 c, 103 d, and/or 103 e. In various embodiments, upon scanning, the authentication application 114 can fetch the decryption mechanism 127 provided by the server 120, and if the decryption mechanism 127 is suitable in relation to the one or more barcodes, including instances involving the scan of the aggregated codes, e.g. barcode 103 d and/or 1033, then one or more features associated with the other applications 115 and/or access application 116 can be accessed. In various embodiments, the decryption mechanism can contain the relevant decryption technique to decrypt either the one or both of the base codes and/or the user-specific codes, in addition to being able to decrypt an aggregated code, e.g. whether generated by an overlaying and/or by bit combinations and/or concatenations. In various embodiments, as stated and implied, the scanner 118 (and the associated decryption mechanism can be provided by the server directly thereto) can be independent of the mobile device and/or more than one device (and/or a different type of device than the mobile device). As stated, and implied above, in various embodiments, the codes 103 a, 103 b, 103 c, 103 d, and/or 103 e can be any suitable matrix code, including but not limited to barcodes.

In various embodiments, the authentication application 114 can send a confirmation back to the server 120 indicating that the one or more barcodes have by the user 102, e.g. once the decryption of an aggregated barcode takes place, the confirmation is sent.

In various embodiments, as shown and as alluded to above, the system 100 can include a host device, such as a server 120, that can be used in accordance with at least one embodiment of the present disclosure. The server 120 can include a memory 122 configurable to include and/or including one or more relevant applications and/or mechanisms for performing one or more operations as outlined in the present disclosure, including a management application 123, which as described above, can communicate directly or indirectly with a user device, e.g. mobile device 110 and/or mobile device 110′, and/or any other suitable device that can generate, utilize, scan and/or transmit barcodes, including a device that can be used with another device to generate an overlaid aggregated code, and provide instructions in relation to and mechanisms enabling the decryption of an encryption mechanism 125 with respect to one or more barcodes.

In various embodiments, as implied and stated above, the one or more individual barcodes and/or the group code can be swappable, and any suitable dynamic encryption or decryption can be used to continuously update the encryption associated with generated scannable barcodes. For example, the management application 123 can revoke the token associated with encryption 125 and/or decryption 127 and in relation to the one or more individual barcodes 103 a and/or 103 b and/or the group or base code 103 c. For example, if an individual changes roles within a group, e.g. from a programming role to an administrative role, the token associated with his or her individual barcode can be revoked, while preserving the token that allows the device associated with him or her to generate, scan, and/or combine the base barcode 103 c. By way of another example, if the individual switches groups in the organization, but the individual's overall role in the organization as a whole remains the same, his or her access to the group barcode 103 c can be revoked (e.g. the token associated therewith is revoked), while his or her individual barcode, e.g. 103 a, remains intact. In various embodiments, whether a group or individual barcode is revoked, the other, un-revoked barcode, can remain intact. In various embodiments, there can be more than one group barcode, which is distinct from other group barcodes, but it can be configured (e.g. the encryption and/or decryption scheme associated therewith) to work with individual and/or user-specific barcodes that work with other group or base codes and vice-versa with respect to the individual and/or user-specific codes.

In various embodiments, the revocation of a base or group code 103 c, can be followed with an updated version of that base matrix code, e.g. barcode, where the updated version can be an entirely new base code for any entirely new group and/or it can be updated in the sense that additional features with respect to the existing group are granted. For example, a group of programmers responsible for task “A” can be subsequently required to also perform task “B,” in which case, the management application 123 can revoke the token associated with the original encryption of the base code, issue a new token that grants access to a first set of features (e.g. with respect to access application 116 and/or other applications 115) that corresponded to the original base code, but additionally, to a new set or second set of features that correspond to the additional tasks. In various embodiments, the updating can be an entirely different scheme, e.g. task “A” is abandoned, and task “B” replaces it, in this case, the updating by the management application 123 can be an entirely different token in relation to the encryption scheme. In various embodiments, whichever scheme can apply, the individual codes, e.g. 103 a and/or 103 b, can remain unchanged and can continue to work without further updating, e.g. the updated base code 103 c is changed without requiring a change to the individual codes 103 a and/or 103 b. In various embodiments, the reverse can take place when appropriate, e.g. the individual codes are updated, and the base can remain the same.

In various embodiments, after the updating, a new aggregated code can be formed by the authentication application 114 and/or any other suitable application, where the new aggregated code can be by overlaying of a user-specific barcode thereon, or any other suitable scheme as described herein (e.g. scanning), and where the individual barcodes remain versatile and distinct, e.g. a user 102 a can use his individual barcode 103 a and a user 102 b can use his individual barcode 103 b with the same updated base or group code, e.g. each individual code is still assignable to the associated respective user and can be distinct from the individual codes associated with other users 'codes. (Alternatively, the base can remain the same and the user codes can be updated, where the updated individual codes can be configured to be aggregate-able with the original base code). In various embodiments, the subsequent aggregation, as stated and implied, can grant each individual user 102 a and/or 102 b access to second, third, etc. additional features, with respect to the other applications 115 and/or access application 116, and where the original aggregated code granted access to an earlier set of features, e.g. first, set of features with respect to the other applications 115 and/or access application 116.

In various embodiments, whether a bit-generation scheme and/or an overlaying scheme is used, the aggregation of one or more barcodes can be with respect to a leveled scheme. For example, a first user, e.g. 102 a, can be associated with a first level of access with respect to access application 116 and/or other applications 115, e.g. one or more tasks of a first-level related to a group of one or more users. For example, the first user 102 a can be a contractor associated with a work-task of an organization, and where the individual barcode 103 a of the first user 102 a, when aggregated with a common base code 103 c of the group, and decrypted utilizing any suitable technique as described herein, grants access to a first level of information. The first individual barcode 103 a can include a first set of bits (e.g. encrypted bits associated with a barcode that can be decrypted using any suitable scheme as discussed herein). A second user, e.g. 102 b, can be associated with a second-level of access with respect to access application 116 and/or other applications 115, e.g. one or more tasks of a second-level related to a group of one or more users. The second user 102 b can be a full-time employee of associated with the work-task and the organization, and where the individual barcode 103 b of the second user 102 b, when aggregated with a common base code 103 c of the group, and decrypted utilizing any suitable technique as described herein, grants access to a second level of information. The second individual barcode 103 a can include a second set of bits (e.g. encrypted bits associated with a barcode that can be decrypted using any suitable scheme as discussed herein), which include the first set of bits and which provide the same first-level of access associated with user 102 a, but contain additional bits that are associated with the second-level access. Yet another, third, individual (not shown) can be associated with a third-level of access with respect to access application 116 and/or other applications 115, e.g. one or more tasks of a third-level related to a group of one or more users. The third user can be a manager of both the first user 102 a and the second user 102 b and can be associated with the work-task and the organization, where the individual barcode (not shown) of the third user, when aggregated with a common base code 103 c of the group, and decrypted utilizing any suitable technique as described herein, grants access to a second level of information. The third individual barcode can include a second set of bits (e.g. encrypted bits associated with a barcode that can be decrypted using any suitable scheme as discussed herein), which include the first set of bits and the second set of bits and which provide the same first-level of access associated with user 102 a and the same second-level access associated with user 102 b, but contain additional bits that are associated with the third-level access. In various embodiments, this scheme can conserve dataspace by having common bits amongst various individual code schemes, while also preserving the versatility of a swappable individual code that can be used with a base code that is common to other users with other individual codes.

In various embodiments, the server 120 can include a confirmation mechanism or application 129, e.g. such as a confirmation log, which receives a confirmation from the user device 110 once the user, e.g. 102 a, has decrypted any matrix code, including an aggregated barcode 103 d. In various embodiments, this enhances security by enabling the host to log activity associated with the matrix codes, including activity related to use of the aggregated codes, which have the group and individual component in relation therewith.

Embodiments are not limited in the above manner, and the above system is merely an exemplary embodiment for implementing one or more features of the present disclosure.

FIG. 2 illustrates an example of a logic flow 200 that may be representative of some or all of the operations executed by one or more embodiments described herein. For example, the logic flow 200 may illustrate operations performed by a system for generating, transmitting, scanning and/or utilizing one or more matrix codes, e.g. barcodes.

At block 205, one or more embodiments of the logic flow 200 may include at least one component as described in the present disclosure scanning an aggregated matrix code to obtain a certain level of access with respect to at least one feature of an application executed on a computer device. The aggregated matrix barcode can be generated using any suitable component as described herein, and it can include a user-specific matrix code that is unique, e.g. uniquely assignable, to at least one user of a group of users, and a base or group matrix code that is unique to that group, where the aggregated matrix code includes a user-specific matrix code uniquely assignable to at least one user of a group of users and a base matrix code associated with the group of users. In various embodiments, as implied and discussed herein, each user-specific matrix code is distinct from a distinct matrix code, e.g. other user-specific matrix code, assignable to each other user of the group of users, but where the common base or group code can be used by each user and with each individual code to form an aggregated code, e.g. aggregated barcode. wherein the distinct matrix code assignable to every other user of the group of users is combinable with the base matrix code. In various embodiments, the component generating the individual barcode, e.g. one or more applications of a server in coordination with one or more applications of a mobile device, can utilize a leveled scheme with respect to user-specific matrix codes, e.g. barcodes, such that one or more individual barcodes are composed of bits that are a sub-set of other individual barcodes, where each subset defines a level of access, and each additional inclusion of bits per user-specific code can provide an additional level of access, while also remaining distinct from all other user codes.

In a networked environment, program modules depicted relative to the computer 402, or portions thereof, can be stored in the remote memory/storage device 450. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers can be used.

The computer 402 is operable to communicate with wire and wireless devices or entities using the IEEE 802 family of standards, such as wireless devices operatively disposed in wireless communication (e.g., IEEE 802.11 over-the-air modulation techniques). This includes at least Wi-Fi (or Wireless Fidelity), WiMax, and Bluetooth™ wireless technologies, among others. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.

The communications architecture 500 includes various common communications elements, such as a transmitter, receiver, transceiver, radio, network interface, baseband processor, antenna, amplifiers, filters, power supplies, and so forth. The embodiments, however, are not limited to implementation by the communications architecture 500, which may be consistent with system 100.

As shown in FIG. 5, the communications architecture 500 includes one or more clients 502 and servers 504. The servers 504 may implement the server device 306. The clients 502 and the servers 504 are operatively connected to one or more respective client data stores 506 and server data stores 507 that can be employed to store information local to the respective clients 502 and servers 504, such as cookies and/or associated contextual information.

The clients 502 and the servers 504 may communicate information between each other using a communication framework 510. The communications framework 510 may implement any well-known communications techniques and protocols. The communications framework 510 may be implemented as a packet-switched network (e.g., public networks such as the Internet, private networks such as an enterprise intranet, and so forth), a circuit-switched network (e.g., the public switched telephone network), or a combination of a packet-switched network and a circuit-switched network (with suitable gateways and translators).

The communications framework 510 may implement various network interfaces arranged to accept, communicate, and connect to a communications network. A network interface may be regarded as a specialized form of an input/output (I/O) interface.

Further, multiple network interfaces may be used to engage with various communications network types. For example, multiple network interfaces may be employed to allow for the communication over broadcast, multicast, and unicast networks. Should processing requirements dictate a greater amount speed and capacity, distributed network controller architectures may similarly be employed to pool, load balance, and otherwise increase the communicative bandwidth required by clients 502 and the servers 504. A communications network may be any one and the combination of wired and/or wireless networks including without limitation a direct interconnection, a secured custom connection, a private network (e.g., an enterprise intranet), a public network (e.g., the Internet), a Personal Area Network (PAN), a Local Area Network (LAN), a Metropolitan Area Network (MAN), an Operating Missions as Nodes on the Internet (OMNI), a Wide Area Network (WAN), a wireless network, a cellular network, and other communications networks.

Further, the features of the devices may be implemented using microcontrollers, programmable logic arrays and/or microprocessors or any combination of the foregoing where suitably appropriate. It is noted that hardware, firmware and/or software elements may be collectively or individually referred to herein as “logic” or “circuit.”

It will be appreciated that the exemplary devices shown in the block diagrams described above may represent one functionally descriptive example of many potential implementations. Accordingly, division, omission or inclusion of block functions depicted in the accompanying figures does not infer that the hardware components, circuits, software and/or elements for implementing these functions would be necessarily be divided, omitted, or included in embodiments.

At least one computer-readable storage medium may include instructions that, when executed, cause a system to perform any of the computer-implemented methods described herein.

Some embodiments may be described using the expression “one embodiment” or “an embodiment” along with their derivatives. These terms mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment. Moreover, unless otherwise noted the features described above are recognized to be usable together in any combination. Thus, any features discussed separately may be employed in combination with each other unless it is noted that the features are incompatible with each other.

With general reference to notations and nomenclature used herein, the detailed descriptions herein may be presented in terms of program procedures executed on a computer or network of computers. These procedural descriptions and representations are used by those skilled in the art to most effectively convey the substance of their work to others skilled in the art.

A procedure is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. These operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical, magnetic or optical signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It proves convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. It should be noted, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to those quantities.

Further, the manipulations performed are often referred to in terms, such as adding or comparing, which are commonly associated with mental operations performed by a human operator. No such capability of a human operator is necessary, or desirable in most cases, in any of the operations described herein, which form part of one or more embodiments. Rather, the operations are machine operations.

Some embodiments may be described using the expression “coupled” and “connected” along with their derivatives. These terms are not necessarily intended as synonyms for each other. For example, some embodiments may be described using the terms “connected” and/or “coupled” to indicate that two or more elements are in direct physical or electrical contact with each other. The term “coupled,” however, may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.

One or more embodiments also relate to apparatus or systems for performing these operations. This apparatus may be specially constructed for the required purpose and may be selectively activated or reconfigured by a computer program stored in the computer. The procedures presented herein are not inherently related to a particular computer or other apparatus. The required structure for a variety of these machines will appear from the description given.

It is emphasized that the Abstract of the Disclosure is provided to allow a reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in a single embodiment for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate embodiment. In the appended claims, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein,” respectively. Moreover, the terms “first,” “second,” “third,” and so forth, are used merely as labels, and are not intended to impose numerical requirements on their objects.

What has been described above includes examples of the disclosed architecture.
